Question: Write the equation of the line in fully simplified slope-intercept form.
Graph: a blue decreasing line on a coordinate grid, passing through the points $(-2, 8)$, $(-1, 2)$, $(0, -4)$, and $(1, -10)$, extending upward to the left and downward to the right.
1. **State the problem:** Find the equation of the line passing through the points $(-2, 8)$, $(-1, 2)$, $(0, -4)$, and $(1, -10)$ in slope-intercept form $y = mx + b$.
2. **Formula:** The slope-intercept form is $$y = mx + b$$ where $m$ is the slope and $b$ is the y-intercept.
3. **Calculate the slope $m$:** Use any two points, for example $(-2, 8)$ and $(-1, 2)$.
$$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 8}{-1 - (-2)} = \frac{-6}{-1 + 2} = \frac{-6}{1} = -6$$
4. **Find the y-intercept $b$:** Use the slope and one point, for example $(0, -4)$.
Since $x=0$, $y = b$, so $b = -4$.
5. **Write the equation:** Substitute $m = -6$ and $b = -4$ into the slope-intercept form.
$$y = -6x - 4$$
6. **Verify with another point:** Check with $(1, -10)$.
$$y = -6(1) - 4 = -6 - 4 = -10$$ which matches the point.
**Final answer:**
$$\boxed{y = -6x - 4}$$
